Have never felt so enthusiastic about a vacuum. Everything is so well considered. I love the dirt sensing which throttles the power to save battery. I like the screen and its clear readout. I love the ease of quick releasing/engaging the accessories and the quick release folding mechanism. The odor neutralizer smells a little like deodorant but is a cool feature if you like it. I turned it as low as possible. The only negative thing I can say is the battery is kind of small for its size. The battery capacity is smaller than an average cell phone battery, but the battery pack is much bigger than a phone. They could package this better if they consulted with a phone manufacturer to include a bigger battery.
